面向对象数据库的安全模型及其应用

近年来,数据库安全模型一直是数据库方面研究的热点。由于关系数据模型是建立在良好的数学模型的基础上,因而成熟的关系数据安全模型已经被提出。而面向对象数据模型本身尚未找到坚实的数学基础,针对面向对象数据库的安全模型研究不多,文章在这方面做了一些尝试,它提出了一种基于视图的面向对象数据库的信息过滤模型。该模型以多级数据模型为基础,综合了视图模型和信息过滤模型的优点;然后给出该模型的评价及其应用。

Security Model for Object-Oriented Database Systems and its Application

In recent years,security model for database has been a focus in the research field of database.Because relation model is based on nicer mathematic,mature security model has been proposed.While object oriented database model himself hasn't seek a strong mathematic base,research about security model of OODB has been slowed.This paper proposes a security model for multilevel object-oriented database systems and gives the implementation of this model.This model is based on multilevel model,composed of view model and message filter ideas.
